After a good night's sleep, I took a second look at this painting and decided that the background needed to be calmed down. I also adjusted the muzzle a bit so it's not so lopsided, and then added more shadow. I think it's a bit better.
This is Jeff, our oldest granddog. Jeff is quite an old guy, now. He leaves horseplay and nonsense to the other dogs - Jeff's idea of a good time is napping in a warm and cozy spot.
